DomainThe acidic domains are probably involved in the interaction with histones.

Post-translationalmodificationsPolyglutamylated by TTLL4, a modification that occurs exclusively on glutamate residues and results in polyglutamate chains on the gamma-carboxyl group. Some residues may also be monoglycylated but not polyglycylated due to the absence of functional TTLL10 in human.

Cellular localizationNucleus. Melanosome. Identified by mass spectrometry in melanosome fractions from stage I to stage IV.
